KNIFE-BOLSTER.

TPECIFECATON forming part of Letters Patent No. 336,107, dated February16, 1886.

Application tiled October 9. 1885.

To @ZZ whom, t may concern.-

Be it known that I, GEORGE HAvnLL, a citizen of the United States,residing in Newark, Essex county, New Jersey, have invented certain newand useful Improvements' in Knife-Bolsters,fully described andrepresented in the following specification and the acco1npanyingdrawings, forming a part ofthe saine.

The object of this invention is to combine a sheet-metal blade and tangwith a solid knifehandle; and i-n order to properly bolster the blade atthe point where the neck of the tang projects from the handle I havedevised a sheet-metal bolster of peculiar construction, and ani therebyenabled to form the entire metal-work of the knife of sheet metal, sothat it may be produced with the ordinary stamping`-tools employed inmaking sheet metal.

The nature of my improvements will be understood by reference to theannexed drawplete knife constructed with my combined bolster andferrule. Fig. 2 is a side View of a knife provided with the bolsteronly, the handle and bolster being shown in section to exhibit thefitting of the bolster to the neck ofthe blade. Fig. 3 is a plan of thebolster; Fig. 4, a side View of the same. Fig. 5 is a Vertical sectionof the bolster shown in Fig. 4, as on line z z in said ligure; Fig. 6, avertical section of a combined bolster and ferrule, takenlongitudinally, as on line rv x in Fig. 3, a slotted collar beingsecured wit-hin the ferrule to brace the tang of the knife, which isindicated by dotted lines therein; and Fig. 7 is a plan of such collarbefore its insertion in the ferrule.

Fig. l shows the application ofthe conibined bolster and ferrule to aknife with a solid handle.

a is the knife-blade; b, a narrow tang adapted for insertion within thehandle d, and c is the neck of the knife, formed wider than the tang,and provided with shoulders to rest upon the ends of the bolster.

e is a flange formed within the bolster to bear upon the end of thehandle.

f is the ferrule, and g is the guide, formed apart from the ferrule, andsecured within the 'metal as thev other parts.

eombined with the sive) may be used apart frointhc ferrule, and

is constructed by forming the opposite halves `(as upon each side of theline .fr x in Figf) from a sheet metal blank of suitable shape stampedto the required form by means of a punch and die, (as is common insheet-metal manufacture,) and finally united together at their joint bysoft or hard solder. The outer end of the bolster is slotted to receivethe neck c, as shown in Fig. 2, and fitted to the shoulder c upon theneck of the blade, so as to brace the blade edgewisc, and the throat ofl the bolster is fitted, as at c" in Figs. 3 and ings, in which Figurelis aside view of a comto fit closely upon the Hat sides of the bladeand brace it laterally. The handle being properly secured to the tang,with its open end in contact with the flange e, the bolster is perfectlystayed upon the blade, and imparts to its neck nearly the same stiffnessas if it were integral therewith.

To ornament the knife, and to impart additional stiffness to thebolster, I sometimes construct it with an attached ferrule, as shown inFigs. l and 6, the opposite longitudinal halves (as at either side ofthe line :v :c in Fig. 3) being formed in a single piece, and when thetwo are united by solder upon their vertical joint they form a combinedbolster and ferrule, as shown in Figs. l and 7.

The slot c2 is formed in the outer end ofthe bolster to iit the neck ofthe blade; but the guide g for'thetang must be situated within the bodyof the ferrule, (to permit the insertion of the handle in the latten)and cannot therefore be stamped from the same piece of Such guide istherefore formed by stamping it from sheet metal separately with itsexterior h't-ted to theinside of the ferrule, and its center formed witha slot, g', to fit the tang b, as shown in Fig. 7. The bolster andferrule being preferably united by a contracted neck, as atl in Fig. l,the

IDO

guide may be placed within the ferrule in contact with such neck, andWithout fastening therein would serve to guide and steady the tangeffectually when the ferrule is secured upon the handle and the tangcenientedin the blade.

I am aware that it is not entirely new to stamp a knife bolster fromsheet metal, as such a construction is shown in German Patent No.18,528, of 1881; and I ain also aware that cast-metal bolsters of formanalogous to mine have already been used, as in United States Patent No.277,932, of 1883. I therefore disclaim the said patents and any con`struction different from that specifically claimed herein.

The method of manufacturewnaniely, the use of sheet metal for both thebolster and the blade-enables me to dispense with the labor of forgingor casting any of the parts, and to secure an article practically equalin strength and beauty to those produced by a more expensive and tediousprocess.

Having thus described the nature and objects of my invention, what Iclaim is* The combined knife bolster and ferrule formed of sheet metal,in two parts, solderedl GEORGE HAVELL.
